Description

Description: This was a part of discussion for https://github.com/envoyproxy/envoy/issues/7728 but a separate issue, to add full or subset of URI Template (RFC6570) based route matching. The URI Template is already used in OpenAPI spec and gRPC JSON transcoding binding.

It will reduce the use case for regex as I see many use of regex is to support this.

Contributor guide

Research direction
Study RFC 6570 URI Template, review Envoy's route matching code, implement parsing and matching of URI templates in the route configuration, and add corresponding tests.
